Solution

1. Preparation

Gather tools: multimeter, flathead screwdriver, socket set, and a replacement fuse if needed.
Ensure the vehicle is parked in a safe location and powered off.
Disconnect the vehicle's 12V battery for safety.

2. Inspect and Clean the Window Switch

Remove the window switch panel using a flathead screwdriver.
Disconnect the wiring harness from the switch.
Clean any debris or corrosion from the switch terminals using electrical contact cleaner.
Reconnect the switch and reassemble the panel.

3. Check and Replace Fuses

Locate the fuse box (typically under the dashboard or in the trunk).
Identify the power window fuse (consult the owner's manual for the exact location).
Remove the fuse using a fuse puller and inspect it for continuity.
If the fuse is blown, replace it with one of the same amperage (typically 20A).
Reattach the fuse box cover.

4. Test Window Motor

Disconnect the window motor from the window regulator.
Using jumper wires, connect the motor directly to the battery (positive to positive, negative to negative).
Observe if the motor operates. If it does not function, replace the window motor.

5. Reassemble and Test

Reconnect any disconnected components.
Reconnect the vehicle's 12V battery.
Test the power windows to ensure they are operating correctly.
